2012 Cadillac CTS Spare Tire
The Cadillac CTS typically comes equipped with a compact or mini spare tire, also known as a "doughnut" tire, which is smaller than the regular tires and only intended for temporary emergency use until the damaged tire can be properly repaired or replaced. This mini spare tire is usually concealed in the trunk space in a dedicated well or compartment, and it should be used only for limited distances at reduced speeds, as advised in the vehicle's instruction manual. The recommended spare tire size varies depending on the model and year of the Cadillac CTS, but a common size for many models is T135/70R18, implying a radial construction with a width of 135mm, a sidewall aspect ratio of 70%, and a wheel diameter of 18 inches. Always verify the appropriate type and size of spare tire for a specific vehicle with the manufacturer's specifications or a trusted tire supplier.
2012 Cadillac CTS comes with 5 OEM tire size options. Select the original equipment the tire size installed on your vehicle to see all spare tires that have roughly the same tire diameter and can be used as a temporary replacement in the event of a flat tire. Remember that load carrying capacity of the spare tire must be the same or higher than the load carrying capacity of the original equipment tires in order to safely support the weight of your vehicle. Refer to vehicle owner's manual or contact Cadillac dealership to confirm the correct 2012 Cadillac CTS spare tire size.
